To all whom t may oon/cern.'-

Beit known that I, FRANK W. ANDERSON, a citizen of the UnitedStates,.and a resident of lVestfield, in the countyT of Chautauqua andState of New York, have invented an Improvement i`n Horse-Hoes, of whichthe following is a specification.

My invention is a disk horse-hoe for use in cultivating grape-vines,raspberries, shrubbery, and plants of various kinds.

The main feature of novelty is the construction and combination of partswhereby a hoe or cultivating-blade may be adjusted to and held atdifferent vertical and horizontal angles.

The invention further includes other features, as hereinafter set forth,and illustrated in the accompanying drawings, in which Figure 1 is aperspective view of my improved horse-hoe. Fig. 2 is mainly a rear viewof the same, some parts being shown in section. Fig. 3 is in part a sideelevation and in part a vertical section of a rear portion of theimplement. Fig. 4 is a perspective view illustrating the construction ofthe shank of the hoe or blade and the portion of the frame to which itis attached. Fig. 5 is a perspective view of a rear portion of theframe.

The frame of the implement or machine to which the cultivating devicesproper are attached is connected by a loose joint 1 with .the axle 2 ofa forward truck, to which a team may be attached in any suitable mannerby means of a pole or shafts. The frame is constructed of two main partsA and-B, which` are formed and constructed as follows: The bar A is benttwice at an obtuse angle, and its rear extremity is bent at a rightangle. The

bar B is bent at an obtuse angle and its rear portion at a right angle.The forward end of the bar B is loosely coupled with the bar A at apoint 3 a short distance in rear of the aXle 2. lt will be noted (seeFig. 1) that the obtuse angles of the bar A are in rear of thiscoupling-point. The inner end of the rear portion of the frame-bar B isloosely coupled at 4 to thebarA. As shown in Fig. 1, such couplingpointis adjacent to the rear angle or corner of the frame A and on the innerside of the same. A block 5 (see Figs. 1 and 4) is arranged at thatpoint, and a short angular bar 6 is bolted to the inner side of it andprovided with an eye which forms a portion of the coupling 4. At therear angle or corner of the frame-bar B is arranged a concavo-convexdisk 7 which serves as a support for suchy portion of the frame and alsoas a steering or guiding device having important functions, as will bepresently described. A handlelS is attached to a frame or block 9, whichis pivoted to the bar B and to which the disk 7 is attached. The bladeor cultivating-hoe 10 (see Figs. 1, 2, and 4) is attached to the T-shape shank 11, having an enlarged flat head 11a, which is provided withholes 12 near its front and rear edges. Two bolts 13 (see Figs. 1 and 4)pass through the block 5, before described, and through certain of theholes 12. By shifting the bolts from one hole to another it is obviousthat the horizontal angle of the blade 10 may be changed as conditionsrequire. Thus it may be placed at such an angle as to draw the earthaway from a row of vines or plants or to force earth toward the same, orit may be placed at right angles to the line of draft. y

The purpose of coupling the frame-bars A and B together at points 3 4,as before described, is to enable the vertical angle of the blade v10 tobe changed. The means for effecting this and for locking the blade inany required position or angle are as follows: The rear end 14 of theframe-bar A is bent upward at a right angle, and a reinforceor separateplate 14'r1 is bolted thereto, as4 shown best in Fig. 5. The upper endof the reinforce 14a is provided with an eye by which it is attached tothe handle 8a. By this means the said handle is rigidly connected withthe framebar A, and it is obvious that by manipulation of thehandle-that is to say, by raising or lowering its outer end-the frame-fbar A may be rocked on the front coupling 1, and the frame-bar B willcorrespondingly rock on thepivots or couplings 3 and 4, so that the twoframe-bars may be'placed in the same horizontal plane as in Fig. 1, orat an angle to each other, as indicated in Fig. 2. A V- shape bracket orkeeper 15 (see Figs. 1, 3, and 5) is attached to the reinforce 14a, andthe same bolts secure it and the reinforce together and to the upwardextension 18 of bar A. Coincident holes are formed in the bracket andthe parts 14 14" to receive a locking-bolt 16. The inner end of thelatter is adapted to enter any one of several registering holes (seeFig. 1) which are formed in the upwardly-projecting portion of anobtuse-angle plate 17, which is bolted to the rear portion of theframe-bar B. (See especially Figs. 1 and 2.) A spiral spring 18 (seeFigs. 1 and 3) encircles the slidable bolt IOO IIO

16 between the bracket 15 and a collar 19, which is fixed on the shaft.The spring therefore tends to force the bolt forward, so as to hold itnormally engaged with the parts having coincident openings as specified.For the purpose of retracting the bolt, and thus unlocking the partswhen desired, l connect it by links 20 with an elbow-lever 21,

(see Fig. 3,) which is pivoted to the handle vconditions the blade 10may be placed and held horizontal, as indicated in Fig. 1, but in 'casean obstruction is encountered-such,for

example, Ias a root or a hard bunch of earth or grass, which the blademight be unable to 4cut or dislodge-the operator presses downward on thehandle 8d and at the same time retracts the bolt 16, whereby the blade10 may be quickly adjusted at an angle, its lefthand lower or rearcorner in such case alone resting and sliding on the ground. Tt is thusadapted to ride safely over a root or other obstruction. vAgain bypressing upward on handle 8a and simultaneously releasing the lock theblade 10 may be placed at the opposite angle, (shown in Fig. 2,) itsright-hand lower corner drawing into the soil, so as to yremove sod orgrass or briars, &c.

These adjustments may be easily and quickly effected, and the blade 10may be also set horizontal when required, in which case it will projectand work beneath a trellis-wire. It will be seen that by provision ofthe T-shape shank 11 I am enabled to provide a long bearing or supportfor the oblong blade, which is a matter of considerable importance, esecially when the blade is made comparative y thin. Thus, as beforedescribed, I rovide for im* portant adjustments of the sait hoe orblade'- namely, for its adjustment at different angles horizontally andvertically, in any of which it may be rigidly secured.

The chief function of the concave disk 7 is to guide or steer and resistthrust of the blade 10. It is journaled upon an axle 21, which is heldin the lower end of arms 22, the same being adjustably attached to theblock or bar 9,which is pivoted at 23 to the rear angle of the frame-barB, as before described. Tt is obvious that by moving the grip end of thehandle 8 to the right or left the frame-piece 9 will swing on its pivothorizontally, and the disk 7 may be thereby placed at different anglesto the line of draft, so as to take more or less earth and offer more orless lateral resistance to the action or leverage ol' blade 10.

The arms 22, which carry the disk 7, are fitted in vertical groovesformed in opposite sides of the thickened piece or block 9 and aresecured adjustably therein by means of screw-bolts 24. The portions ofthe bars which fit in said grooves are parallel and straight andprovided with a series of holes to receive the said bolts, so that theyare adapted for adjustment vertically as may be required. lt will beseen that the portions of the bars 22 which extend below the block 9 arenot in the same vertical plane with those portions which lie in thegrooves. In Fig. 1 they are shown extended rearward. It is obvious thatby detaching them from the block Q and substituting one for the otherthey may be so placed that the lower pendent portions will projectforward instead of rearward. The importance of this will appear from thefollowing statement: When the hoe or blade 10 is placed horizontal andat the lateral angle indicated in Fig. 1, it will tend to draw outward,and this tendency is counteracted by the disk 7, whose concave side istoward the blade. lf, on the other hand, the blade should be placed atthe opposite angle, it would tend to crowd toward or in the direction ofthe disk 7, and hence to resist such tendency the concave side of thelatter should be reversed or placed outward. Thus whenever the angle ofthe blade is reversed the disk 7 is reversed correspondingly in order toresist side thrust. When concaveV or dished side of disk 7 is toward theright, by moving handle 8 laterally a little to the right the disk willbe placed at angle opposite the angle of the blade, and it will drawinto the soil and offer lateral resistance 'enough to keep the blade 10from drawing too far under a trellis-wire. In brief, by turning the diskslightly right or left the resistance to the lateral draw of blade 10may be increased or lessened at will and a furrow of corresponding widthwill be cut. In brief, the disk 7 and its handle S serve as means forgovering the lateral cut of the blade 10 with accuracy and ease. This isvery advantageous, especially for guiding the blade past posts andstakes and under wires and bars or rails that support the wires, &c. Itwill be further apparent that when the arms 22, in which the disk 7 is journaled, are inclined rearward the side leverage or IOO IIO

presssure on the disk is less than it would be V ISO and the adjustmentof the disk 7 farther forward or back is also relatively important. Itwill be further noted that by suitable manipulation of the handle 8 thedisk 7 may be turned on the pivot 23 to cause it to take more or lessearth, and thus cut awider or narrower furrow, as conditions mayrequire, and this change of inclination or horizontal angle of the diskmay be varied at the will of the operator to cause the hoe as a whole towork in the required manner.

W'hen the ground .is dry and hard, it may be desirable to weight thedisk 7 in order to make it take into the ground to a greater depth thanwould otherwise be the case, and in such event it would be advisablethat the standards or bars 22 should be inclined forward, so as torelieve strain on the pivot-bolt.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
